dateKeys-dart

Stage 7a: the vectors of Go for the locator

tool/locator_go_vectors.go runs package locator of datekeys-go at c531e93,
the draft v0.12, in its module, without changing it, and writes what Go
gives, with the texts of its errors:

- locator_uris.json: CheckURI and Address.Host on the 247 addresses of
  testdata/vectors/locator.json and on 2 800 more, built at every edge of
  spec 44.1 and drawn from a seed: IPv4 and IPv6 in every notation that
  netip.ParseAddr accepts or rejects, zones, mapped, NAT64 and 6to4
  addresses, the first and last address of every IANA block and their
  neighbours, long and punycode labels, local names, ports, percent
  signs, dot segments and CIDs; netip.ParseAddr and String on 1 700
  strings; and publicIP, reached with go:linkname, on 868 byte strings.
- locator_vectors.json: the texts of the other cases of locator.json;
  PlaintextLength from -4100 to 16484; Unmarshal on 482 plaintexts; Marshal
  at every limit and boundary of the padding; Open on 118 sealed locators
  of four rounds, edited or with other releases and profiles; Open past
  1 MiB of plaintext, read through io.LimitReader; the envelope, its rest,
  Hide and the split of NewEnvelope; Info.Extension, Info.OpenLocator and
  ParseInfo; locator.Standard as a registry; and capsule.Open of a fixture
  whose .dkk carries datekeys.capsule.

crypto/rand.Reader is a ChaCha8 of a fixed seed, so every run writes the
same bytes. The Dart constants hold the whole of the first file and a
part of the second, for the tests compiled to JavaScript.
